The Five Digits Test in the assessment of older adults with low formal education: construct validity and reliability in a Brazilian clinical sample

Abstract Introduction In the assessment of older adults with very low formal education, typical tests of selective attention and inhibitory control are biased by reading abilities. In this sense, we aim to assess the psychometric characteristics of the Five Digits Test (FDT), a numerical Stroop paradig...

Rev. méd. Chile; 145 (8), 2017
Background: According to the Chilean National Health Survey (2009-2010), 17% of people aged 15 years or more have depressive symptoms. Thus, freely-available, easily-administered, and highly sensitive screening tests for depression are needed in clinical and research settings. Aim: To evaluate the psych...

Are traditional body fat equations and anthropometry valid to estimate body fat in children and adolescents living with HIV?

Braz. j. infect. dis; 21 (4), 2017
Abstract The aim of this study was to assess the validity of traditional anthropometric equations and to develop predictive equations of total body and trunk fat for children and adolescents living with HIV based on anthropometric measurements. Forty-eight children and adolescents of both sexes (24 boys)...

Selenocysteine modulates resistance to environmental stress and confers anti-aging effects in C. elegans

Clinics; 72 (8), 2017
OBJECTIVE: The free radical theory of aging suggests that cellular oxidative damage caused by free radicals is a leading cause of aging. In the present study, we examined the effects of a well-known anti-oxidant amino acid derivative, selenocysteine, in response to environmental stress and aging using Ca...

Hyperin protects against cisplatin-induced liver injury in mice

Abstract Purpose: To evaluate the effect of hyperin in cisplatin-induced liver injury in mice. Methods: Mice were pretreated with hyperin at doses of 25 mg/kg and 50 mg/kg, respectively, for six days, and intraperitoneal injection of cisplatin (40 mg/kg) was administrated one hour after the final intr...

Perconditioning combined with postconditioning on kidney ischemia and reperfusion

Acta cir. bras; 32 (8), 2017
Abstract Purpose: To evaluate if combination of perconditioning and postconditioning provides improved renal protection compared to perconditioning alone in a model of renal reperfusion injury. Methods: Thirty rats were assigned into 6 groups: normality; sham; ischemia and reperfusion; postconditionin...

Abstract Purpose: To investigate the inflammatory and redox responses to teduglutide on an animal model of laparotomy and intestinal anastomosis. Methods: Wistar rats (n=62) were allocated into four groups: "Ileal Resection and Anastomosis" vs. "Laparotomy", each one split into "Postoperative Teduglut...

Corneal angiogenesis based on different protocols of alkaline cauterization in murine models

Acta cir. bras; 32 (8), 2017
Abstract Purpose: To establish and compare protocols of alkaline cauterization for inducing corneal angiogenesis in murine models. Methods: Twenty-four adult Wistar rats were distributed into four groups (G1, G2, G3, and G4). The right eye cornea from each rat was cauterized using filter paper (3 mm), ...
